Step #3 Use the straight edge to run from this side cross hair point to the elevator control horn. Make the line go directly through the elevator horn clevis hole.

Use masking tape on the side of the fuse at the rear to mark this line. I start about 10 to 12 inches ahead of the stab and go to the tail post. This insures I have the right spot covered with tape. As before you can put the tape down and then draw a sharpie line on it or use the tapes edge as your straight line. I use the tapes edge.
